TFICE LOUIS DUBRULLE, OF PARIS, FRANCE.

LUBRICATING-OIL DISTRIBUTER.

To all whom 'it may concern:

Be it known that I, Louis DUBRULLE, citi- Zen of France, residing at Iaris, in the said Republic, have invented new and useful Im- 5 provements in Lubricating-Oil Distributers, (for which I have obtained a patent in France, No. 363,123, bearing date February 10, 1906; inItaly, No. 231171, May 31, 1906, and in England, No. 17,168, July 30, 1906,) of which the following is a specification.

In lubricating oil distributers used hitherto for motor cars, the oil is forced to the distributer by putting it under pressure in the reservoir, either by means of a portion of the exhaust gases from the motor or by means of a small air pump. Sometimes the oil is supplied to the distributer'by an independent pump controlled by the motor.

The present invention relates to a lubricating oil distributer that is independent of the reservoir, which may be placed at any part of the vehicle. The distributer is controlled by the motor and draws oil directly from the reservoir, transmitting this oil under pressure to the diverse parts to be lubricated.

The apparatus consists, essentially, of a primary pump feeding a distributer and returning the excess of oil to a feeding tank, 0 and of secondary pumps sending the oil from drop ing tubes into corresponding conduits which lead to the points to be lubricated, the piston of the primary pump and those of the secondary pumps being mounted on the same rod, to which reciprocating movement is contributed by any suitable means.

The invention is illustrated in the accompanying drawings.

Figure 1 is a longitudinal vertical section, on line a-b of Fig. 2 or Fig. 3, of an apparatus for distributing under high pressure oil drawn from a separate reservoir. Fig. 2 is a transverse section on line c-d of Fig. 1. Fig. 3 is a longitudinal horizontal section on line c-f of Fig. 1.

rThe apparatus here shown comprises three dropping tubes, although the number may be varied as may be necessary, the distributer being extended for the purpose.

The apparatus consists of a distributer body 3 having a cylindrical bore 4 subdivided into a number of small cylinders, 6, by corks or partitions 5. In each of these small cylinders Works a piston 7, the pistons 7 and 5 the cylinders, 6, constituting a plurality of Specification of Letters Patent.

secondary pumps. The several pistons are fixed to a rod, 10, common to them all. The end of this rod is connected with a bell crank lever 1 centered on a bracket 23 and pivoted at its end 2 to a rod to which a reciprocating movement is given by a cam, or the like, keyed on one of the reducing shafts of the motor.

The oil is pumped by the piston 8 of the suction and force pump and through the passages of the casting 9, this iston being also mounted on the rod 10. T e pump 9 is connected by an inlet pipe 13 with the oil reservoir, .which may be at any part of the vehicle. The pump forces the oil through passage 12 into a compartment or header, 11, whence it flows down the dropping-tubes or sight feeds 1,4, at a rate controlled by the needle valves 15, into the compartments 2O having glazed fronts 21, through which the proper working of the dropping-tubes may e observed. From these compartments the oiliiows through ducts, 16, to the respective cylinders or secondary pumps 6. The latter communicate by passages 17 with the discharge pipes 18; the said passages 17 may be closed by spring pressed balls '19 which act as valves for the pumps. Excess of oil is returned, from the header, 11, to the reservoir through a duct 24 communicating with the discharge pipe 25. The controlling lever 1 and with it the rod 1() carrying the pistons is returned by the spring 22.

The apparatus operates as follows The motor having been started, the controlling rod, operated by the cam or eccentric, draws down the lever 1 which is then returned by the spring 22, so that the rod 10, with the three pistons 7 and the main piston 8, receives a reciprocating movement. In consequence, the primary pump 9 sucks oil from the reservoir and forces it to the droppingtubes or sight feeds 14, which distribute it in the desired quantity, under control of the needle valve 15, to each of the pump cylinders 6, the oil thus distributed drop by drop or even in fine streams, is forced by the secondary pistons 7 to the parts to be lubricated. The excess of oil brought to the distributer by the main pump 9 but not distributed by the dropping-tubes, is returned to the reservoir by the pipe 25.

I claim In a lubricator, a primary pump, a plurality of secondary pumps, and dischargepipes therefor, a rod on Which all the pistons of leading, respectively, to and from the header,

the primary pump being arranged to supply the header With lubricant and to remove the excess therefrom, the secondary pumps being arranged to take lubricant from the sight feeds and deliver it to the discharge pipes, 10 and means for reciprocating the rods.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.

LOUIS DUBRULLE.
